IMPROVEMENT IN MINERS LAMPS.

Specification forming part of Letters Patent No. 176,650, dated April 25, 1876; application filed February 17, 1876.

To all whom it may concern:

Be it known that I, JOHN Q. LEE, of Plymouth, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps, of-

In order to enable others skilled in the art -to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, which forms a part of this specification, and in which- Figure 1 is a section of the top of my lamp, also a blank top punched or cut out of one piece of sheet metal. Fig. 2 is a section of the top of my lamp. also blanks of sheet metal, being a modification of the plan shown in Fig. 1. Fig. 3 shows the ordinary soldering thehinge-strap of metal to the top of the lamp.

In these figures, A is the top of the lamp, and B the hinge. The top A is punched or cut from one piece of sheet'metal. .The part A is larger in diameter than the part A which is concave, or formed as shown by the section of the top in Figs. 1 and 2, and which may be attached thereto or be a part thereof. The part A is turned up and over the projecting flanges'a of the part. A securing the two parts together, thereby forming a top of two thicknesses, which are united without the use of solder.

The objection to soldering or to the use of solder is that when the lamp is exposed to a strong draft the flame from the spout is blown over the top and melts the solder, unhinges the top, and thereby renders the lamp useless.

B is the wire hinge passed through the eye in thetop, then' down through the inclined wall of the-lamp, and clinched or otherwise secured therein. The eye of the top is formed by the connecting-piece, as shown by the blank top in Fig. 1.

The conformation of this device is such that a very strong and secure top is fitted to the lamp.

Having thus fully described my invention,

what I claim as new, and desire to secure by JOHN Q. LEE.
